Ultraviolet lighting platform

Abstract

A method and apparatus for genomic or proteomic research to visualize fluorescent-labeled DNA, RNA or protein samples that have been separated for documentation and analysis. The apparatus includes a novel radiation source for uniformly irradiating the samples which comprises a grid constructed from a continuous, serpentine-shaped ultraviolet light producing tube that is strategically formed to provide a multiplicity of side-by-side, immediately adjacent irradiating segments. In one form of the invention the apparatus also includes a first conversion plate that is carried by the housing at a location intermediate the radiation source and the sample-supporting platform for converting the radiation emitted from the source to radiation at a second wavelength.

1 . A radiation source for substantially uniformly irradiating a spaced-apart surface and radiation source comprising a grid for emitting ultraviolet radiation constructed from a continuous, serpentine-shaped ultraviolet tube that is strategically formed to provide a multiplicity of side-by-side, immediately adjacent irradiating segments.  
   
   
       2 . The radiation source as defined in  claim 1  in which a plurality of said adjacent irradiating segments are at least partially coated with phosphor.  
   
   
       3 . The radiation source as defined in  claim 1 , further including dispersion means superimposed over said grid for controllably dispersing the ultraviolet radiation emitted from said grid.
